确保Hadoop已正确添加到系统环境(例如HADOOP_HOME)。
遇到问题:`java.lang.RuntimeException: java.lang.RuntimeException: Error while running command to get file permissions : ExitCodeException exitCode=-`。码报
问题原因:在Hadoop的码报dnf时装源码bin目录下缺少两个关键文件。
解决步骤:访问下载链接获取缺失文件。码报完成下载后,码报太阳分时指标源码重启并重新执行操作。码报试客新版源码若仍出现错误,码报可能是码报缺少`MSVCR.dll`运行库。下载并安装此运行库以解决问题。码报
执行操作后,码报问题应得到解决。码报确保所有步骤正确执行以避免遇到更多错误。码报
